- Direction (including strength of conviction in that direction)
- Timing
If you enter near your exit stop then you risk very little on each trade.
Location
Traders use many tools to find a location for entry. I mainly use Market Profile. Others use Pivot Points, Fibonacci and visually identified support and resistance areas.
Direction
You need to be convinced that the market will move in the direction that you are about to enter your trade. I use a proprietary indicator called Alpha for this which gives me both direction and strength of possible move. You can use an oscillator or momentum or other indicator for this information. You need to find something the suits your style and personality. What works for fellow traders might not work for you.
Timing
If you are entering a counter-trend trade then it is best to enter on market excess - when the market has overshot and over-reacted and there is a high chance of a pullback. Because I trade the equity indices I use $TICK to measure this. I have an indicator that I have created that keeps track of $TICK through the day and tells me when $TICK has reached an extreme and plots that on the chart for me and rings a bell to warn me. I call this indicator TimerA1.
